BICYCLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 484,941, dated October 25, 1892.

Application filed January 12l 1892. Serial No. 417,859. (No model.) Patented in Germany .Tune 7, 1891, No. 59,865, and in England June 8,1891,N0.9,695.

A Bicycles, (for which I have obtained Letters Patent in Germany, No. 59,865, dated June 7, 1891,and in England,No. 9,695, dated June 8, 1891,) of which the following is a specification.

The object of my invention is to provide a `new and improved support in which bicycles can be so held as not to injure the rubber tires and to permit of turning the Wheels for oiling and cleaning them.

The invention consists in a bicycle-support composed of two united standards, a vertically-adj ustable plate on each standard,which plates are provided at their upperends with forks for receiving the crank-shaft, a brace resting on the support for supporting the front end of the bicycle-frame, and a hookbar on said support for embracing and holding the crank-shaft in place on the upper ends of the vertically-adj usted plates.

The invention also consists in the construction and combination of part-s and details, which will be fully described hereinafter, and nally pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my improved bicyclesupport. Fig. 2 is a similar view, on an enlarged scale, showing part of a safety-bicycle held in the same. Fig. 3 is a detail View of the extensible sliding plate. Fig. 4 is a perspective view of the roller-frame. Fig. 5 is a detail perspective view of the spring used to hold down the front wheel.

Similar letters of reference indicate corresponding parts. Y

The support consists of two side pieces or standards a, which are flared outward at their lower ends to form legs or feet, and said standards are connected with each other by transverse bolts b. To each standard a sliding plate c is fitted, which can be held at any desired elevation by a bindingscrew cZ, the threaded part of which is screwed into the side of the standard, and which binding-screw passes through a vertical slot c3 in the sliding plate c'. The sliding plates c slide in recessed parts in the outer faces of the standards and are guided by the side edges of the.

recesses. The upper ends of the sliding plates c form forks b for receiving the crankshaft of the bicycle, or the bearings for said crank-shaft. For holding said bearings the supports p are provided on the outer side4 with upwardly-projecting Iianges q, whichpreventlateral movement of said crank-shaft when in the forks, as the flanges project above the sides of the bearings of the crankshaft.

In the drawings, g is the crank-shaft; h,the`A bicycle to be held. r As the'plates c can be` adjusted vertically, the support can be adjusted in height or width to suit any wheel. In case both wheels of the bicycle are to be held above the floor this can be accomplished by means of the rod Za, which is forked at both ends, the prongs of the lower fork embracing the lower transverse bolt b of the support and the upper fork engaging the frame of the bicycle at the proper point, in safety-bicycles at the angle formed by the backbone and steering-head. The said rod 7c consists of two parts, one of which can slide in the other-,one of them being provided with a binding-screw, so as to adjust said rod to any desired length. rPhe upperbolth of the supportcarriesarocking holding device composed of two parts ZZ2, the part Z being provided at its upper end With a hook m. The two parts Z Z2 are held together by means of a binding-screw n in the piece Z', as shown in Fig. 2, said screw passing through a slot ot' the part Z2. Those edges of the parts Z Z2 facing each other are provided with teeth which can interlock, and thus serve to make the connection between the parts Z and Z2 more rigid. After the parts Z and Z2 have been loosened as much as desired the hook m is passed over the crank-shaft and then the IOO parts l and Z2 are adjusted at the proper length and drawn together, whereby the hook 'm securely holds the bicycle on the support.

In case a tricycle is to be held the transverse rod which is below the rear axle of the tricycle is placed into the forks p. In case a tricycle or ordinary or high wheel is to be held the plates c are replaced by the plates c2,

(shown in Fig. 3,) provided at their upper ends with a tubular extension fr, adapted to receive the sliding rod t, which can be locked at any desired elevation by means of ascrew s. The fork p is formed at the upper end of said rod t, and at said fork the inclined tlangesq' q are formed. When ordinaries are to be held, the upper bolt b, connecting the standards a, is removed, so as to permit the turning of the larger wheels. It is" evident that with this stand the rubbertires of tliecycles arenot injured, as no part of the weight of the cycle rests upon the same. The driving# wheel is at all times' heldclear. fromthe floor and can be turned for the purpose of exam ining, repairing, or oiling the same.

With this device the safetyebicyele can' be used as a home trainer, in which casea frame y, provided with grooved rollers'rv, is placed under the rear wheel, which rests on said rollers. When the person'occu'pies the wheel, the weight of said person swings the sameftoward the rear until the tire of the rear. wheel is in contact with the rollers o o, wherebythe desired friction is produced without in any way injurionsly adecting the tire, whether the same be a solid tire, cushioned tire, or pneumatic tire. If, however, the pressure upon the rollers o o is t-oo great, the tensionspring shown in Fig. 5 can beV used, which consists of a spring provided at one end with a hook z, and at. the other end with' a prong z', which prong, if desired, maybeprovided withv screw-threads. The prong z is secured in the floor either by driving itin or screwing itin, and then the hook'zis engaged with the rim of the front wheel and draws the same downward, thereby raising the rear wheel more or less to prevent too much friction between the tire of the rear Wheel and the rollers v o.

` ends with forks for receiving the crank-shaft of a bicycle and of a rod having its lower end supported by the standard and its upper end engaging the front part of the bicycle, substantially as set forth.

3. In a bicycleesupport, the combination, with t-wo standards, of vertically-adjustable plates on the same provided at their upper ends with forks forreceiving the-crankshaft lof the bicycle and an extensible swinging hook-bar on a'bolt uniting the standards, substantially asset forth.

4. In a bicycle-support, the combination, with two standards, of' vertically-sliding 'plates in the same provided at their upper ends with forks for receiving the crank-shaft of the cycle, a-swinging extensible bar composed of two sections mounted on one of thebolts uniting the standards, and a hook on the upper end of said extensible bar, substantially as set forthl 5; In: a bicycle-support, the combination,

' with two standards, of `verticallyadjustable `plates on `the same, a tubular extension on each plate, a rod held ineach extension and provided at its u'pper'end with' a fork, and a screw' for locking each rod in the' extension, substantially as set forth.

In testimony that I claim-theforegoing as my inventionI havesigncd my name'in` presence of two subscribing witnesses.
